obtaining a blended red-green-blue (RGB) image frame of a scene; and
performing, using at least one processing device of an electronic device, an interband denoising operation to remove at least one of noise and one or more artifacts from the blended RGB image frame in order to produce a denoised RGB image frame;
wherein performing the interband denoising operation comprises performing filtering of red, green, and blue color channels of the blended RGB image frame to remove at least one of the noise and the one or more artifacts from the blended RGB image frame;
wherein the filtering of the green color channel of the blended RGB image frame produces a denoised green color channel; and
wherein the filtering of the red and blue color channels of the blended RGB image frame is based on image data of the denoised green color channel.
